What is the first step to solve the equation 16x-21 = 52? 1 Add 52 to both sides

2 Add 21 to both sides

3 Subtract 21 from both sides

4 Subtract 52 from both sides

2) Add 21 to both sides

Step-by-step explanation:

When solving for , our goal to isolate such that we have set equal to something.

Therefore, we want to start by adding 21 to both sides. This leaves us with and we are one step closer to isolating .

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
